OpenRFID ERP Gateway: Open-Source Tally & SAP Connector
Open-source Python and Node.js starter scripts for translating LLRP and handheld RFID tag scan streams into Tally Prime XML, SAP Service Layer JSON, and REST Webhooks.
Quick Start / Clone Repository
Project Overview
Enterprise gateway connecting physical RFID readers and handheld scanners directly to Tally Prime, SAP Business One, SAP S/4HANA, Zoho Inventory, and custom REST API endpoints. Includes verified Tally TDL XML envelope generators, SAP Service Layer OData authentication clients, in-memory tag deduplication filters, and local SQLite offline buffer queues.

Frequently Asked Questions
How does OpenRFID ERP Gateway integrate with Tally Prime? ↓
It connects directly to Tally Prime's integrated HTTP server on TCP Port 9000 using standard TDL XML <ENVELOPE> payloads. It creates automated Stock Journal and Physical Stock vouchers without manual operator intervention.
Does it support SAP S/4HANA and SAP Business One? ↓
Yes. For SAP S/4HANA, it connects via RFC BAPI (BAPI_GOODSMVT_CREATE) or OData v4 for Goods Movement 101/311. For SAP Business One, it dispatches JSON payloads to the Service Layer REST API (POST /b1s/v2/InventoryGenEntries) mapping serials to EPCs.
How does the gateway handle high-throughput dock door tag bursts? ↓
The gateway features an in-memory Disruptor ring-buffer with a 3-second dwell-time debounce filter. It filters multipath duplicates and micro-batches up to 1,000 tags per second into single idempotent ERP vouchers.
What happens if factory Wi-Fi drops during an inventory audit? ↓
All scanned tags are stored locally in an encrypted SQLite Write-Ahead-Log (WAL) queue. As soon as connectivity restores, an automated background worker syncs the queue with deterministic SHA-256 deduplication.
